3M Science

  • 3M Scotchgard Protector

    Scotchgard™ Protector for Roofing Shingles

    Almost all roofs are susceptible to black streaks from algae growth. Algae resistant shingles with Scotchgard™ Protector provide long-lasting roof protection against ugly black streaks. Our industry leading protection comes from having at least 10% copper containing granules evenly distributed across the shingle surface, which are tested by a third-party laboratory.

    Only Atlas Roofing and Malarkey produce shingles featuring Scotchgard Protector that provide roof protection against black streaks caused by algae for years to come.

  • A Roof that Beats the Heat

    A Roof that Beats the Heat

    3M™ Cool Granules are the perfect example of 3M science applied to life. The solar reflective nature of the granules allow them to reflect sunlight and heat that other shingles would typically absorb.

    Urban Heat Island Effect
    In some cities, the temperature can be 3 or 4 degrees warmer than the temperature in surrounding rural areas because of pavement and lack of green space. 3M™ Cool Roofing Granules help roofs reflect heat, decreasing the effects of urban heat islands while still being affordable.
